To alleclzom it may concern:

Be it known that vze, vV1LLIA.\1 R. Fox and. Emmi 11V. Fox, citizens ofthe United Sta es, residing at Grand Rapids, in the vented certain newand useful improvements in Scales andScale Attachments for;Type-,Writing l aiachines, of Wlii li the following is a specificetien.

This invention relates to improvements in scales and scale attachmentsfor typeivi'iiiiig machines.

The objects of this invent-ion a1'e,First, teprovide an improvedcenstructien cf anmilar scale cause on a typewritiiig machine; second,to provide an improved eajustalile paper scale esgecially adapted foruse in conjunction with an ammlar scale.

Further objects relating to details of cell sti'uction will definitelyappear from the cle tailed description to follow.

accomplish the objects of our lIlVQll tion by the devices and meansdescribed in the following specificaticn.

The invention is clearly defined and pointecl out in the claims.

our invention is clearly illustrated in El! companyi'ng drawing,iicrming a gar't specification, in which,

of the scale wheel somewhat similar to a face gear. Secured to theplaten head G" is a ratchet wheel E. The annular scale wheel E isrecessed to receive the same. The pawl e is secured to the scale wheel Eon a suitable pivot and is held normally in engagement with the ratchetwheel E by the spring c. On he face of the annular scale wheel'E issecured the stop tooth F, which extends out beyond the periphery andfills one of the notches E; the proper lo cation is to have it fill thenotch bearing the highest numeral on the scale. An adjustable tooth F isprovided which is formed on the end of the spring F" which is bent toembrace the hub of the hub G" and is given a helical form to urge itnormally into engagement with the notches E on the face of the annularscale wheel E so that this tooth F can be adjusted to any point on thescale by simply pushing out toward the end and moving it or the platento the relative position described. .Where the device is used on theimproved Fox front-strike machine, a stop pin B is pro.- vided, detailedat Fig. 6, and its position shown in Fig. 2, for engaging these teeth 1*and F, the stop pin being adjustable so that it can be thrown into andout of relation with the stop teeth on the annular scale.

Shoulders, with a bulging part between, are cut in the stop pin and aspring 13 provided to engage the same and hold the pin yieldingly inposition in whichever position it is adjusted, out or in. The spring Bfully appears in Fig. 2; the position of its free end appears in Fig. 6.Where the machine is of the under-strike type, a dittcrcnt stop is used,like that appearing in Figs. '10, 11 and 12, the stop being a slide Hwhich is adjustable on the carriage lever or handle J. A pin H isprovided to lock the stop in position by projecting through a slot htherein, the pin being urged downwardly by a spring H. The slot Happears in Fig. 1E! and is indicated by dotted lines in Fig. 10. The endof this stop it is moved into position as indicated in 14), and it canobviously be withdrawn out platen scale. Then the annular scale isrevalved with,the left hand until the fixed tooth F strikes or contactswith the stop F. The stop is'then withdrawn and the platen turned untilthe date line appears. Notice 5 on the annular scale .whet number standsincense opposite the stop P; turn the annular scale backward and thenmove the movable tooth l into the notch thus indicated. This, inoperation, will give the necessary spaces on the paper between the lastentry on the sheet and the new date line. If it is desired to condensethe work more, the tooth may be advanced one or more notches, each notchrepresenting a space. that, after inserting the main record sheetwiththe carbons, the stops can be turner to prdper position andadditional. can be inserted into the typewriter, as the occasion arisesfor making out smaller statements, and the whole will be properly spacedin making the additional. entries so that complete carbon copies forrecord purposes can be kept while short invoices or items are beingfilled out.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:
